Sgo all whom it may concern:

Be it known thatl, REUBEN O. STUTsMAN, a citizen of the United States,residing at of Iowa, have invented certain new and useful Improvementsin Tires for Vehicle- Wheels; and l do declare the following to be afull, clear, and exact description of the inuse the same,.reterencebeing had to the accompanying .drawings,.and-.to the letters and figuresof reference marked thereon, which form .apart of this specification.

Fi ure 1 shows'a binding wire after the locking coil has been formed atone end; 2 'is -a side view of the rubber tire after the wire has beeninserted.; Fig'. 3 shows, on a largersoale, the ends of the rubber andthe binding wire 'ust after "thestraight end has rough the end ot thefirst coil; Fig. e is a similarly enlarged view, showing the wire afterthe final locking coil has been formed; and Fig. 5 is a side view of thenished tire.

Heretofcre solid rubber tires have been manufactured with Wires passedthrough them forholdingatogether the ends of the rubber, toit imparting,a, certainK amountof ty andfor holdingtlie tire'inplace upon diffiuties-have be'enniet wi A, gboth inthe manu actu-rei andfinthe'use ofsuehltirwwhich it is the object of the In making my improved tire l takethe following st s: The rubber A is cut to the proper lengt this havinga small central engitudinal passage or aperture for the in sertion ofthe wire. The 'wire is also cut to the requisite length. One of theprincipal. purposes of a supplemental wire 1s to obviate entirely thenecessity of cement as commonly used in securing tires, eithercushionedor pneumatic, to rims. .After the Wire has beencut to length a series ottight lefthand coils of very short pitch are formed at one end, as shownat C. 'Then the other end ot' the wire is passed through the rubberuntil it rojects from one end, the end with the rubber. The coil C is ineect a tube at one endof the wire which has an internal Specca'tibn ofLetters Patent.

diameter just sufficient to permit theopposite free end of the Wire tobe passed through t e it lengthwise. Then the straight end of wire c ispassed through the coil C andat a place Abeyond the initial bend c2 aseries of tight right-hand coils of short pitch is formed I as shown atC. These coils are independent of each other that is to say, thelefthand coil is at one end of the wire and the-ri hlt-.fv

hand coil is at the other end.. The resu t is that the two ends of thewire are not only held with firmness because of vtheir interlocking, butthis iirnmess is augmented because of the opposite relations 'of thecoils.

By examining the drawing -it will be seen that the fastening consists oftwo endwise. abutting coils, and that each of these coils from end toend surrounds a straight section on the other end ofthe Wire. 'In thisres e'ct ther fastening is materially different 'reni what it wouldwire.

' What l claim is: l

i. A rubber vehicle tire consisting oit' a piece of rubber having anaperture longitudinally through. it and a wire inserted in the saidaperture, the wire having atoneenda tubular ortion, and its o posite endBeing assed t rrough the said tu ular portion, and aving its tree endcoiled about the portion 'of the wire immediately back of theA tubularportion, substantially as set forth.

2. A vehicle tire consisting of a rubber having an aperture through itand a wire inserted in the said aperture the wire y lanportien formed bycoilingthelwikre in one direction, y and-its oppositeen'll'gl),eingVdassed through saidStubular-portibn,:and having its free cn'd co'iledabout the 'portion of the Wire immediately backl of the tubularportieri and in a direction' opposite that of the coil of the saidtubular portion, substantially as described.

in testimony whereof,l aHx my signature, in presence of two witnesses.
